Extreme ultraviolet emission lines of Ni xii in laboratory and solar spectra [PDF]

open access: yes, 2004
A linear force-free field solution is presented in cylindrical coordinates, formulated in terms of trigonometric and Bessel functions. A numerical exploration has revealed that this solution describes magnetic field lines that meander in Cartesian space, as well as field lines that lie on toroidal flux surfaces.

Detecting Solar Flare Precursors Using DEFT

open access: yesThe Astrophysical Journal
The Detection and EUV Flare Tracking (DEFT) tool automatically identifies flare precursors in extreme ultraviolet (EUV) observations in a fast and consistent manner, with minimal computational overhead. DEFT currently uses GOES/SUVI 304 Å observations to

Bridging Horizontal to Vertical Radiative Cooling

open access: yesAdvanced Science, EarlyView.
Radiative cooling materials are mature but only work facing the sky, confining them to rooftops. Instead of developing new ones, this system bridges existing horizontal coolers to vertical windows using blades outside the glass. On an occupied urban building, windows stay up to 1.4°C below air temperature while preserving daylight, outward views, and ...

Extreme-ultraviolet Synthesis of Nanojet-like Ejections due to Coalescing Flux Ropes

open access: yesThe Astrophysical Journal Letters
Detection and characterization of small-scale energetic events such as nanoflares and nanojets remain challenging owing to their short lifetimes, small spatial extent, and relatively low energy release, despite their potential role in coronal heating ...

The propagation and damping of slow magnetoacoustic waves in the solar atmosphere [PDF]

open access: yes, 2012
The propagation and damping of slow magnetoacoustic waves in the solar atmosphere is investigated, with particular emphasis placed on waves with periodicities of five minutes. The basic model of a uniform temperature loop is extended by the addition of

The Link between Nonthermal Velocity and Free Magnetic Energy in Solar Flares

open access: yesThe Astrophysical Journal Letters
The cause of excess spectral line broadening (nonthermal velocity) is not definitively known, but given its rise before and during flaring, the causal processes hold clues to understanding the triggers for the onset of reconnection and the release of ...
